Maria Barria, 72-year-old, takes part in a fishermen's protest on a bridge in Ancud on Chiloe Island, some 1,229km southern of Santiago de Chile, Chile, 08 May 2016. Fishermen have been protesting because of a ban imposed on fishing in local waters due to the red tide phenomenon in the area. The red tide is caused by the excessive proliferation of microalgae with high concentrations of toxins, which can cause illness in humans and animals. Consumption of seafood contaminated by the red tide is blamed for 23 deaths in Chile since 1972. (Photo by Damian Parra/EPA)
